If you like your donuts big, a little bread-y, with a kiss of grease then you need to try the ones from here. I got the Boston cream donut, which had a sweet but light filling, not quite custardy but more like a buttercream. I only wish my donut had more of it. If you're taking your donut to go, expect any frosting on top to smear onto the paper bag. No fear, you can always dip your donut back into it.
I didn't have the chance to try anything else from here, but the donut was pretty solid and I'd come back to try other donuts or food (but donuts first).
